Now this is really annoying. I've listed some ways of entering
Old Norse characters - but it has become a bit messed up in transit.
Therefore, I've written down simple instructions in an html file and
included it here as an attachment. Simply click on the attachment
listing and it will open up in your browser. If it fails to do that,
I suggest a croquet mallet - it often corrects many of the minor
computing difficulties that I've encountered - and I suspect that it
would serve anyone else equally well.
